Recommeded BGP Session for IBGP & MP-iBGP

[hshong]

Hello..

My customer has a plan to deploy BGP Route-Reflectors for normal iBGP & MP-iBGP(vpnv4) on MPLS L3 VPN network.

The Route-Reflecors are C7200(NPE-1G) systems

50 PE routers will make IBGP&MP-iBGP sessions with Router-Reflecor

I'm wondering how many bgp sessions are recommeded per router.

It will determine the scablility of Router-Reflector

Could you give me any information or related cisco document ?

Thanks

Hi,

It depends on your total memory,IOS version,available min memory,number of routes.

It won't be much of a help bu you can find some information from this link

Thanks for your reply.

Is there any limitation number of bgp neighbor(session) per router,something like PDB(Protocol Discription Block)?

Not that I know of.

Limitation comes from memory,routes.
